RELIABILITY ANALYSIS OF NOSQL DATABASES

The article deals with NoSQL databases and their reliability. There were developed analytical and simulation failure models for NoSQL databses using queueing theory. Mechanisms for automatic data recovery after node fault were described. The authors estimated node recovery time and probability of DoS while reading in NoSQL database. The results of model experiments were analyzed in the article.

Keywords: NoSQL database, failure model, operating time between failures, probability of a denial of service, reliability
